news Technical performance characteristics, product availability, and physical forms of carbon, silicon carbide, alumina and aramid fibres will be examined along with three classes of matrix materials in each case. In addition, manufacturing processes and current uses will be evaluated and a forecast for future uses and markets will be made. The survey, which will be on a group sponsorship basis, was expected to start towards the end of 1980 and last for a period of five months. Further information can be obtained from: Dr Thomas R.

Batelle, Columbus Laboratories, 505 King Avenue, Columbus, Ohio 43201, USA. Fig. 5 Under-view of the trailer of an articulated lorry showing the Mathweb side under-run safety guard Road-accident-victim-catcher

It used to be called a cow-catcher and it was sported on the front of steam locomotives to give a reminder to animals that had strayed in front of the train to remove themselves from the track. To-day's side under-run safety guard (Fig, 5) is designed to fit on the side of articulated trail-ers to prevent unfortunate unprotected road users from incurring serious injury by being knocked or thrown under the rear wheels. Produced in anticipation that legislation will make such guards compulson/ in many European countries, BP Technical Development have made a guard by the Mathweb process - a new manufacturing technique w h i c h uses g l a s s f i b r e reinforced C e l l o b o n d p o l y e s t e r resins. The advantages of such a guard are high strength combined with low weight. The Mathweb under-run guard weighs 25 kg, an a d d i t i o n a l grp c l a d d i n g sheet weighs 15 kg, and the guard can withstand the impact of 200 kg weight at 18 km/h perpendicular to


the panel without breaking. In the case of a heavier impact, the guard should rupture without the formation of sharp edges.

The Intercontinental Conference on

Advanced technology in materials engineering organized by SAMPE, will take place on 12-14 January 1981 in Cannes, France. The papers, most of which will be directly concerned with composite materials,

will be presented under the following categories: material properties; new products and material concepts; design allowables; applications; and quality control. Further information from: SAMPE, PO Box 613, Azusa, California, USA, or M r J. BeBossue, 41, rue Phelipeaux, 69100 Villeurbanne, France. The 36th Annual Conference and Exhibition of the SPI Reinforced Plastics/Composites Institute will be held at the Sheraton Washington, Washington DC, USA on 16-20 February 1981. Monday, 16 February will be designers' day. There will be two concurrent all-day engineering seminars, one on basic principles and the other on advanced materials, processing, and design.
