On March 10, company of United States of Dongli composite material (CMA) announce to roll out CMA 3900 series formally beforehand dip makings, the design that involves numerous field publicly at the same time is allowable database. Association of American car engineer (SAE) one-way belt and fabric product established the 3900-2 that material committee is not aimed at Dong Li especially new data standard AMS 6891. Dong Li expresses, new material already can be purchased, undertake attestation through AMS 6891 standard. Manual of CMH17 of below one edition will announce 5 batches 3900 beforehand dip makings designs concessional data.
